[0011 ] Figure 1 illustrates vehicles travelling in proximity in accordance with an example;
[0012] Figure 2 illustrates vehicles travelling in proximity in accordance with a further example; and
[0013] Figure 3 illustrates a vehicle proximity warning system in accordance with an embodiment.
Description of Embodiments
[0014] Figure 3 shows a vehicular proximity warning system 100 in accordance with an embodiment comprising a plurality of vehicular electronic devices 105.
[0015] With reference to Figure 1 , there is shown first and second vehicles 101 , comprising a bicycle and a motor vehicle for exemplary purposes. Each vehicle 101 may have a vehicular electronic device 105. The term “vehicle” as used herein may include any travelling thing, including pedestrians, non-propelled and propelled vehicles and/or self-propelled and motorised vehicles. [0016] At least one of the electronic devices 105 comprises an indication device 107. In use, the system 100 outputs an indication using the indication device 107 of at least one of the electronic devices 105 according to a proximity of the first and second electronic devices 105.
[0017] The indication device 105 may output an audible indication. As such, with reference to Figure 1 , when the bicycle 101 is in proximity of the vehicle 101 , one or both of the respective electronic devices 105 may output an audible indication to warn the cyclist or motorist of proximity of the other motor vehicle or bicycle.
[0018] The system 100 may determine a virtual geo-fence 102 around each vehicle 101 and determine when an electronic device 105 of another vehicle 101 breaches the virtual geo-fence 102. The virtual geo-fence 102 may comprise a radius of 50 m in embodiments.
[0019] Each electronic device 105 may take the form of a small form factor portable electronic device 105 comprising internal battery supply for the powering thereof. As such, each vehicle 101 may carry the portable electronic device 105. In embodiments, the electronic device 105 may comprise a communication device executing a software application.
[0020] Figure 3 shows wherein the electronic device 105 comprises a processor 108 for processing digital data. In operable communication with the processor 105 across a system bus 1 16 is a memory device 1 14. The memory device 1 14 is configured for storing digital data including computer program code instructions. In use, the processor 108 fetches these computer program code instructions and associated data 1 18 for interpretation and execution for the implementation of the computational functionality provided herein. The computer program code instructions may be logically divided into a plurality of controllers 1 15.
[0021 ] The controllers 1 15 may comprise a tracking controller 1 16 for tracking the relative positions, directions and or the like of the electronic devices 105 and an alerting controller 1 17 for controlling the indication device 107 according to the proximity of the electronic devices 1 15. [0022] The data 118 may further comprise settings 1 19 for adjusting the operation of each electronic device 105, including a proximity threshold and, in embodiments, route data 120 as will be described in further detail below. In embodiments, the settings 190 may be used for adjusting the radius of the virtual geo-fence 102.
[0023] Each electronic device 105 may comprise a GPS receiver 115 for determining a location of the electronic device 105. The electronic device 105 may comprise an I/O interface 115 for interfacing with various peripherals, including the indication device 107 and a vehicle subsystem 106 in embodiments which will be described in further detail below.
[0024] In embodiments, the system 100 may determine a speed of a vehicle 101 and dynamically adjust the size of the virtual geo-fence 102 accordingly. For example, for a vehicle travelling at 100 km/h, the system 100 may adjust the radius of the virtual geo-fence 102 to 200 m as opposed to 50 m for when the vehicle 101 is travelling less than 50 km/h.
[0025] In embodiment shown in figure 1 , the virtual geo-fence 102 is circular. However, in embodiments, the system 100 may determine a travel direction of the vehicle 101 and wherein the virtual geo-fence 102 is distended in the direction of travel. For example, the virtual geo-fence 102 may be generally triangular shaped, projecting in front of a vehicle 102 so as to warn of other vehicles in front, but not necessarily of other vehicles passing close behind.
[0026] In embodiments, the system 100 may calculate a distance between the vehicles 110 and wherein audio played out by the indication device 107 indicates the distance. For example, the electronic device 105 may comprise a speech synthesiser which synthesises the determined distance to speech so as to, for example, indicate to the cyclist that there is a vehicle within 47 m of the cyclist.
[0027] In embodiments, the system 100 determines a radial direction of the electronic devices 105 with respect to each other, such as through 360°. For example, with reference to Figure 1 , the system 100 may determine that the motor vehicle 101 is at 45° with respect to the cyclist 101. The cyclist electronic device 105 may play out such a radial direction. The radial direction may be categorised such as a wherein, for example, the synthesiser audio specifies that there is a vehicle “at 3 o’clock” or alternatively “to the right”.
[0028] In embodiments, the settings 1 19 specify the type of vehicle such that the synthesised audio may specify the type of vehicle. For example, the synthesised audio may specify that “there is a motor vehicle/truck/pedestrian/bicycle” within proximity. In embodiments, the system 100 may dynamically adjust the sizing of the virtual geo-fence 102 according to the type of vehicle wherein, for example, for fast travelling vehicle types, the system 100 may increase the size of the virtual geofence 102, such as to 100 m for motor vehicles as opposed to 50 m for pedal propelled vehicle such as bicycles and 10 m for pedestrians.
[0029] With reference to Figure 2, the system 100 may determine travel vectors 103 for the vehicles 101 , each vector 103 comprising direction and magnitude. The system 100 then predicts the proximity according to the respective travel vectors 103. The example shown in figure 1 shows a motor vehicle 101 travelling in a northerly direction at high speed and a bicycle 101 travelling in a westerly direction at a lower speed. The system 100 then determines the contemporaneous intersection of the vectors 103 to predict proximity and provide warnings accordingly. In the embodiment shown in Figure 2, the system 100 may determine contemporaneous intersection within a virtual geo-fence 102 which may be sized and shaped including in the aforedescribed manners.
[0030] In embodiments, the I/O interface 1 15 of the electronic device 105 may interface with the vehicle subsystem 106 to determine forward or reverse operation thereof. For example, the vehicle 101 may be an electric mobility scooter which is put in reverse to reverse from a driveway onto a street. In this example, the I/O interface 1 15 detects the reverse operation of the mobility scooter from the vehicle subsystem 106 thereof to determine that the vector 103 is in the opposite direction and therefore will contemporaneously intersect a vector 103 of a vehicle travelling down the street. [0031 ] In further embodiments, the system 100 determines travel routes for each vehicle 101 and predicts the proximity according to the routes. [0032] For example, one or both vehicles 101 may be travelling along a route wherein the system 100 determines the contemporaneous intersection of the routes or alternatively a route and a travel vector 103 to predict proximity.
[0033] The route may be an active route wherein the electronic device 1 05 itself is providing navigation or alternatively interfacing with an external navigation system via the I/O interface 1 15.
[0034] Alternatively, the route may be a historical route which is recorded by the electronic device 105. For example, the bicycle 101 may travel along a set route to work every morning and the system 100 may therefore determine that the bicycle vehicle 101 is about to turn right into a lane according to the historical route down which a motor vehicle 101 is currently travelling so as to provide a warning accordingly.
[0035] The electronic devices 105 may comprise short-range communication interfaces 1 10. The system 100 may determine the proximity according to short-range communications between the short-range communication interfaces 1 10.
[0036] The proximity may be determined according to a received signal strength indication (RSSI) of a short-range communication received by a short-range communication interface 1 10. For example, each electronic device 105 may generate periodic transmissions using the short-range communication interfaces 1 10 wherein other electronic devices 105 within proximity may determine the distance according to the received signal strength thereof.
[0037] Additionally, or alternatively, each electronic device 105 may comprise a data interface 109, such as a GSM interface which sends data packet across a communication network. Each electronic device 105 may transmit location data determined from the GPS receiver 1 14 to a server 1 12 which may maintain a location database 1 13 of the vehicles 101. As such, the server 1 12 may determ ine the proximity in any of the aforedescribed manners and transmit electronic communications to electronic devices 105 of vehicles 101 and proximity or predicted is going to be in proximity. [0038] The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that specific details are not required in order to practise the invention. Thus, the foregoing descriptions of specific embodiments of the invention are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed as obviously many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, thereby enabling others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated. It is intended that the following claims and their equivalents define the scope of the invention.
